Abstract
The invention provides a method for extracting cellulose from peony seed shells and relates to a plant cellulose extracting method. The method for extracting the cellulose from the peony seed shells comprises the steps of firstly washing and drying the peony seed shells, using a smashing machine to smash the peony seed shells into powder, then using 1:2 by volume ratio of benzene-ethyl alcohol mixed liquid to perform soaking for 1-2 hours, sequentially using 5%-10% by mass of inorganic base solution, 30%-35% by mass of sodium xylene sulfonate water solution and 2:1 by volume ratio of hydrochloric acid-absolute ethyl alcohol mixed liquid to treat filtered residues, and finally obtaining the cellulose. The method uses abandoned peony seed shells to extract the cellulose, a process working procedure is short, the requirement or equipment is not high, cost is low, environmental pollution is low, and extracted cellulose is high in purity.
Description
Technical field
The present invention relates to cellulosic extracting method in plant, be specially one and extract cellulosic method from peony seeds shell.
Background technology
At present, because tree peony not only has higher ornamental value, more can be used as medicinal material and cultivated widely for developing agricultural product and health products etc.The peony seed oil extracted from peony seeds is nutritious and unique, and has higher health-care function, is therefore subject to more and more consumers, and peony seed oil secondary industry is in continuous expansion thereupon, but also creates a large amount of peony seeds shells.Peony seeds shell is many is abandoned by enterprise for these, bring bad impact, and peony seeds shell is not also well utilized to environment.Containing a large amount of celluloses in peony seeds shell, cellulose is the important source material in the field such as paper industry and textile industry, and from plant, extract the main method that cellulose is still these industries acquisition fibrous raw material at present.Discarded peony seeds shell is effectively utilized again, and is therefrom obtained cellulosic material, the environmental problem that peony seeds shell brings can not only be solved, can also be turned waste into wealth, brought certain economic benefit to enterprise.At present, although occurred manyly extracting cellulosic method from various plant material, but floristics is various, its chemical composition of different types of plant also has larger difference, therefore finds a kind of cellulosic method of extraction of applicable peony seeds shell significant.
Summary of the invention
Object of the present invention is just to provide one and extracts cellulosic method from peony seeds shell, and in order to effectively to be utilized by discarded peony seeds shell, the method technological process is simple, not high to equipment requirement, cost is low, and environmental pollution is less.
For achieving the above object, technical scheme of the present invention is: one extracts cellulosic method from peony seeds shell, comprises the steps:
(1), by removing after the peony seeds shell after peony seeds cleans, dries, be broken into Powdered with pulverizer;
(2), by pulverous peony seeds shell volume ratio be that the benzene-alcohol mixeding liquid of 1:2 soaks 1 ~ 2h, after filtration, after washing, leave residue;
(3), by the residue mass fraction of step (2) be 5 ~ 10% inorganic alkali solution at 70 ~ 80 DEG C, soak 1 ~ 2h, then filter, leave residue;
(4), by the residue mass fraction of step (3) be the xylene monosulfonic acid sodium water solution boiling 30 ~ 60min of 30 ~ 35%, then filter, leave residue;
(5), by the residue volume ratio of step (4) be that the hydrochloric acid-absolute ethyl alcohol mixed liquor of 2:1 soaks 30 ~ 60min at 60 ~ 70 DEG C, wherein, the concentration of hydrochloric acid is 5mol/L, after filtration, washing, dry after, obtain cellulose.
Inorganic alkali solution described in step (3) is NaOH solution or KOH solution.
Beneficial effect: the present invention's benzene-alcohol mixeding liquid carries out preliminary treatment to remove the dissolved organic matter impurity in raw material to raw material, and then adopt inorganic alkali solution, xylene monosulfonic acid sodium water solution and hydrochloric acid-absolute ethyl alcohol mixed liquor to process raw material successively, thus effectively by peony seeds shell with cellulose the composition such as the hemicellulose of tight weave in and lignin remove, make the cellulose extracted have higher purity.
